Abstract
Abstract A flexible cryogenic fluid transfer system wherein the fluid conduit is held in spaced relation to the outer flexible hose by an improved support system. The support system is characterized in that a hollow support member surrounding the fluid conduit is provided with a plurality of helicly disposed slotted apertures on its surface. A continuous filament is wrapped around the support member and those portions of the filament in the slotted apertures serve to position and hold the inner fluid conduit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
100 words
A means for supporting an elongated object in spaced relationship to and within a hollow elongated object comprising: a plurality of slotted apertures in said hollow elongated object disposed substantially perpendicular to the axIs of said hollow elongated object, said apertures being spaced one from the other, each of said apertures beginning and ending in the outside surface of the hollow elongate object at a different location than the adjacent apertures; a filament wrapped around said hollow elongated object and disposed in said apertures; whereby said elongated object is held within and in spaced relationship to said hollow elongated object.
Claim 2
Dependent Claim
100 words
A means for supporting an elongated object in spaced relationship to and within a hollow elongated object comprising: a plurality of slotted apertures in said hollow elongated object disposed substantially perpendicular to the axIs of said hollow elongated object, said apertures being spaced one from the other, each of said apertures beginning and ending in the outside surface of the hollow elongate object at a different location than the adjacent apertures; a filament wrapped around said hollow elongated object and disposed in said apertures; whereby said elongated object is held within and in spaced relationship to said hollow elongated object.
Claim 3
Dependent Claim
22 words
A support system according to claim 1 wherein the apertures extend no deeper than one-half the cross-section of said hollow elongated object.
Claim 4
Dependent Claim
24 words
A support system according to claim 1 wherein the apertures are disposed in a helical relationship to the axis of the hollow elongated object.
Claim 5
Dependent Claim
25 words
A support system according to claim 1 wherein the hollow elongate object has a shape complimentary to the shape of the elongated object being supported.
Claim 6
Dependent Claim
23 words
A support system according to claim 1 wherein the apertures are of equal depth from the outside surface of said hollow elongate object.
Claim 7
Dependent Claim
197 words
A flexible cryogenic liquid transfer system for transferring a liquid cryogen from a storage dewar to an apparatus to receive the cryogen and be cooled thereby comprising in combination: a liquid transfer conduit; disposed around and in fluid tight relation to a portion of either end of said transfer conduit, means for engaging receiving means on the storage dewar on one end and on the apparatus to be cooled on the other end to hold the transfer conduit in fluid tight relation therebetween; surrounding a portion of each of said first mentioned means and the transfer conduit therebetween a jacket; disposed within a substantial portion of said jacket and spaced apart from said transfer conduit a length of flexible tubing; a plurality of slotted apertures in said tubing disposed substantially perpendicular to the axis of said flexible tubing, said apertures being equally spaced one from the other, each aperture beginning and ending in the outside surface of said flexible tubing at a different location than the beginning and ending of the adjacent apertures; a filament wrapped around said flexible tubing and disposed in said apertures to support said transfer conduit in spaced relation to the hollow tubing.
Claim 8
Dependent Claim
197 words
A flexible cryogenic liquid transfer system for transferring a liquid cryogen from a storage dewar to an apparatus to receive the cryogen and be cooled thereby comprising in combination: a liquid transfer conduit; disposed around and in fluid tight relation to a portion of either end of said transfer conduit, means for engaging receiving means on the storage dewar on one end and on the apparatus to be cooled on the other end to hold the transfer conduit in fluid tight relation therebetween; surrounding a portion of each of said first mentioned means and the transfer conduit therebetween a jacket; disposed within a substantial portion of said jacket and spaced apart from said transfer conduit a length of flexible tubing; a plurality of slotted apertures in said tubing disposed substantially perpendicular to the axis of said flexible tubing, said apertures being equally spaced one from the other, each aperture beginning and ending in the outside surface of said flexible tubing at a different location than the beginning and ending of the adjacent apertures; a filament wrapped around said flexible tubing and disposed in said apertures to support said transfer conduit in spaced relation to the hollow tubing.
Claim 9
Dependent Claim
25 words
A cryogenic transfer system according to claim 6 wherein the transfer conduit is held in vacuum-tight relationship to said first mentioned means and said jacket.
Claim 10
Dependent Claim
31 words
A transfer system according to claim 6 wherein the jacket is a flexible hose, the tubing is of a flexible synthetic material, and the filament is continuously wrapped around the tubing.
Claim 11
Dependent Claim
24 words
A transfer system according to claim 8 wherein the apertures in the flexible tubing extend no deeper than one-half the cross-section of the tubing.
